To allwkom z'tmqy concern:

Be- '1; known that I, EDWARD L. Mneirm, a citizen of the UnitediStat'es, residingat New York, in the eounty of :New York-and Stateoir'New York, haveinvented certain new and; useful Improvements in Feed-Gages for use on Printing-Presses, of: which the following isaspecification.

This invention relates-j tofeed gages for use On printing presses,of'the %eneral type shown for instance in my. w 2%1-556 of'May 17th,1881, in whichthereis a prong for insertion through a hole'or slit inatympan sheet, two armsadaptedto overlie the tympan sheet, a verticalhea-d member eonnecting the prongand the arms, and a tongue projecting"thnough an opening: in the he'ad member and having bent po'rtionsgripping the edges of -the two armsgwhereby the tongue may be slid todifferent positions a-long the arms so that it' will project hold of thetongue on the arms dependson the resiliency offthe parts, andilhavekfound that the tongue wi1l'not ioe firm1yheld in position at theouter ends of the arms, particul'arly' after-the device has been'inusefor some time. Accordingly, onelof thieobjects of thepresent inventionis to provide a' construction in which 'thetwo armsaforesaidfarearrangedso that they diverge from the headmember with whichithey areintegral, the distancebetweentheiarlns adj'acent; the point wheretheyijoin thehead member being such that when the gripping portionsofthe tongue are over theedges of the arms adjacent this point, the gripping portions will be firmly held: other words, the distanoe'betweentherarms'atthis 40 point is slightly larger than the distanoe hetweenthe gripping portionsof the tongue I so that the tonguewillbefrictionallyheld.

And the tongue is adjusted to difi'er'ent positions toward the outer endofthe two arms'the friction is increased because the.

' arms-\diver'ge away from tl e head member. The resnltof this is thatthe gripi'of the at t e outer ends of'the arms as at' thei inatent: No.

A further object ofmy invention is to provide a device'of the kind abovereferred to. which maybe readily V stamped out of a single piece of-suitable material, in which the connection between the prong and headinernhert'are decidedly strengthened and stifi'ened, and in'whichprovision is' made for; an; opening in the head member through which theadjustable tongue. may project which; opening? extends tothe lower edgeozfithe head member, thoughthe surrounding edges? defining.- the opening; are everywhere mbroken.

Thishead-piece has usual extension symmetrically on opposite sides of theconnection with the prong and has backwardly turned wings 1e and downwad pr jections or points 15 which n'iay e forced into the tympan sheet tohold the device in aosition. Extending baclivardly from the head member12 is a pair of integral arms, which for reasons hereinafter explained,diverge away flOl each other, beginning with their point of connectionto the head mem her. At their outer ends these arms are as usualprovided on their outer edges with cut-out portions 17.

The usual form of adjustable tongue is shown in Figs. 2 and 3 andcomprises a tongue proper 18 extendingfrom a cross plate 19 having anupstanding finger part 20 and dependent gripping fingers 21. In use thetongue extends through an opening in the head member, as shown in Fig. 1for instance, and the tongue is engaged with the arms by slipping thegripping fingers 21 over the arms at the cutouts 17, after which thearms 16 are pressed toward each other so that the gripping fingers mayengage the edges of the arms inwardly of the cut-outs 17. Obviously, inorder to hold the tongue on the arms the distance between the grip pingportions of the tongue should be less than the distance between theouter edges of the arms at any point of their length excepting only thecut-out portions 17 so that the tongue will be held frictionally at anyadjusted position along the arms. If the arms were merely parallel,instead of di vergent, repeated pressing together of the ends of thearms would tend to destroy their resiliency so that after a time thetongue would not be held firmly if adjusted to a position toward theouter ends of the arms. With the present construction there is alwaysthe proper tension to hold the tongue in any adjusted position.Obviously, the inherent resiliency of the gripping fingers 21 is of someassistance.

The opening 22 through the head member 12 is formed in the blankillustrated in Fig. l. as shown, with its lower edge, which is the onenearest the prong 10, formed on a curve indicated at 24:, and the rootof the tongue is bifurcated to constitute the edges defining this curvedlower part of the opening 22. When the device is formed up from theblank shown in Fig. 4 the prong 10 is bent under the head-piece 12 asshown in .=;1gs.

5 and 6, so that the bifurcations of the prong are at rlght angles tothe head-piece, as is also the curved edge 24. The result of thismanipulation is that there is an opening in the head-piece defined byunbroken surnnding er yes of the material, which openndc rem top tobottom of the head a tongue 18 projecting through this opening may, ifdesired, lie fiat on the tyinpan .heet. In addition, it will be seenthat the bifu cations of the prong join the head-piece by way of anupward and outward curve, which strengthens the connection between theprong and the head-piece and minimizes the possibility of breakage atthis very important point. Obviously, the action upon the metalconnecting the prong and the head-piece in inserting the prong throughthe tv ipan sheet is to bend the metal along a horizontal line ofjunctions, and if the bend originally formed at this point were simplyin a horizontal line crystallization would take place after a while,with resultant fracture. With my construction however. the original bendof the metal is not in a horizontal line merely but is a twisted bend soto speak which resists crystallization.

It will be understood that the device formed from the blankshown in Fig.4 is of thin sheet metal of uniform gage throughout, and tl at thepunching out and forming up is done by means of dies in any usual orpreferred manner. I find that the form of blank shown in Fig. lis veryeasy to manufacture because the outer edge is struck with a singlestroke, simplifying the operation and lessening the cost of manufacture.

I claim:

1. In a device of'the kind described, a 1.00 prong member, an aperturedhead member integral therewith, divergent arms extending from the headmember substantially as and for the purpose described, and a tonguehaving portions including theouter edges of 1 5 said arms and extendingthrough the aperture in the head-piece.

2. In a device of the kind. described, a prong member, an apertured headmember integral therewith, divergent arms extending from the head membersubstantially as and for the purpose described, the prong nember havingbifurcations which connect to the head member and define the lower edgeof the aperture therein, said bifurcations being disposed atright anglesto the head member, and tongue having portions including the outer edgesof said arms and extend inc; through the aperture in the headpiece.

In a device of the kind described, a prong m mber, an apertured headmember integral therewith, arms extending from the head membersubstantially as and for the purpose described, the prong member havingbifurcations which connect to the head member and define the lower edgeof the aperture therein, said bifurcations being disposed at rightangles to the head member, and a tongue having portions including theouter edges of said arms and extending through the aperture in the headpiece.

l. In a device of the kind described, a prong member and a head memberintegral therewith, the prong member having bifurcations disposed atright angles to the head member and gradually curved thereinto.

5. In a gage of the class described C0111- prising a head piece and apenetrating prong 10 integral therewith the line of junction between thehead piece and the prong being on a gradual curve. a

6. In a gage of the class described cornprising a head piece and anintegral penetrating prong the latter having curved bifurcations whichconnect the prong to the head piece.

In testimony whereof I affixniy signature;
